Minimum-cost dimensioning model for common channel signaling networks under joint performance and reliability constraints

An efficient method is developed to calculate the joint performance and reliability measure, called performability, between an arbitrarily chosen source-destination pair of signaling points in a CCS (common channel signaling) network. An iterative optimal dimensioning procedure is developed to minimize the total link cost of the network subject to required end-to-end performability constraints between the signaling points. Using examples, it is shown that the proposed dimensioning method overcomes the shortcomings of a conventional link-by-link dimensioning method
